Specification of Eetters Patent,

Patented July as, rare.

Application filed February 27, 1911. Serial in. mine.

To all whom it may concern:

Be it known that I',M1enAEL D. MURRAY,-

a citizen of the United States of America, residing at-WeStHOmeStead, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Switching A pliances, of which the following is a speci cation, reference being had therein to the accompanying drawing. p

This invention relates to a switch applianc'e, and the objects of my invention are to provide a hovel electric turn-table that can be advanta ously' used in. large freight yards for acilita'ting the switching and making-u of trains.

With te aho've and such other objects in view as may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts to be hereinaft claimed. y

Reference will now be had to the drawings forming a part of this specification, wherein there is illustrated a referred embodiment of the invention, but it is to be understood that the structural elements thereof are susceptible 'to such changes as fall -within the scope of the ap ended claims.

In the drawings: igure 1 is a diagrammatic plan of the switching appliance in accordance with the invention. Fig. 2 is an enlarged vertical longitudinal sectional view of the same. Fig. '3 is an enlarged vertical cross sectional View of the appllance. Fig.

4 is an enlarged plan 'ofa portion of the tracks adjacent to the appliance, showing automa'tic chuck blocks adapted to be used in connection with the appliance. Fig. 5 is a longitudinal sectional view of the same partly in elevation. Fig. 6 is a diagrammatic view illustrating theelectrical connections between the various electrically op-v erated elements of the invention.

A switching appliance in accordance with this; invention embodies an electrically operated turn-table, and electrically operated chuck blocks in connection with the tracks terminating at t'he! turn-table for preventing rolling stock from passing onto the turntabie e'xce'ipt when the turn-table is properly positione The turn-table comprises an annular founer specifically described and thendation 1 located in a pit or well 2 lined with concrete or other material 3, the bottom of 55,

the well or pit 2 bein" inclined anaconverging to the center thereof for drain ng purposes. Centrally of. the pit or well 2 there is a structure 4 having a drain o ening 5 formed therein, and this .opehin" is in communication with the pit or we 12 b openings 6 and 7 formed a bed plate 8 and a central post 9 carried thereby, said bed plate-being embedded in the bottom imin of the pit or well 2.

ou'ntedupon the annular foundation 1 within the pit or Well 2 is a circular endless track or rail 10 and upon this rail is adapted to travel flanged Wheels 11 mounted upon axles 12 journaled in depending hangers 12, carried by I-beams lfl: arranged in the pit or well 2 and having the u per ed" es thereof flush with the ground line 15. T e I-b'eams 14 aresup orted by the u r" hts 16 of a circular p atfortn l7 Have u y 'mjouuted upon the post 9 of the bed plate 8, said platform having bearing 18 for the ax'ie's 12.- Upon the platform 17 is mounted a suitable source of power, as'a combustion engine adapted to drive an electric "enerater 20 located upon said latform, th 5 generator serving as a source of 'el-eetrieatenergy for motors 21 and 2l su orte'd by han ers'Q'Q from the I-beam 14. q I e armature s an of the motor 21 is connected direct to one of the axles 12. Upon the I-bearn's 14 are mounted sleepers are mounted rails constitutin" 3eralle tracks 24and 25. The supports 6 are provided with an extension 28 for a cab 01' ties or sleepers 23 and upon these ties or house 29 containing a controller adapted to bebo'perated by the attendant of the turnta'le; v

To prevent rollih" stock from being shifted olf of the trac s 49 when the tracks 24 and 25 of the turn-table do not properly aline with the trackse I employ 'electric'ally operated chuck bloc s, these hlocks being located at the ends of the tracks 49 in levers of each pair having the outer ends thereof provided with chuck blocks 54 normally extending over the rails of the track 49. The inner ends of the levers-52 and 53 are slotted as at 55. The slotted ends of the levers 52 and 53 overlap and slidably mounted in the said slotted ends of said levers is a pin 56 carried by an extension 57 t which projects from an armature 58.

The reference character 59 denotes a casing located in the upper edge of the pit or well 2 and in which is arranged the armature 58. The casing 59 is provided with an open end 60 and arranged within said casing is a coiled compression spring 61 adapted to normally hold the armature 58 and the extension 57 thereof whereby the chuck blocks 54. will be positioned over the rails of the main track 49.

Arranged between the I-beams 14 at the ends thereof and supported by brackets 62 are electro-magnets 63. A magnet 63 is adapted to be positioned in alinement with the casing 59 so that when the magnet is energized it will contract the armature 58 carrying its respective extension 57 therewith. As the extension 57 moves toward the magnet 63, the levers. 52 and 53 will be rocked so as to remove the chuck blocks 54: fromthe main track 49. The turn table is locked by the attractive force between the magnet 63 and the piston 58, as long as the magnet 63 is energized. When the magnet 63 is deenergized the turn table is released and the chuck blocks are automatically shifted to operative position through the medium of the expansion of the spring 61.

Reference will be had to Fig. 6 of the drawings, wherein there is illustrated what is believed to' be suflicient electrical connections for understanding the operation of the switch appliance.

The reference numeral 65 denotes an electric generator or other source of electrical power in circuit with bus bars 66 and 67.

68 denotes a controller within the cab 29, and which is provided with a controller arm 69 adapted to beswung to engage contacts 70, 71, and 72. The controller arm 69 is.

connected by a feed wire 73 to the-bus bar 66. The contact 72 is connected by a wire 74 to the motor 21, and said motor by a wire 75 to the bus bar 67. This connection is made with the source of electrical energy 65. The contact 71 is also connected to the motor 21 by a wire 76 and said motor by a wire 77 to the bus bar 67. When the controller arm 69 is swung to engage the contact 71, the turn-table is revolved in one direction, the circuit being from the source of electrical energy 65 through the bus bar 67, wire 77, motor 21, wire 76 to the contact 71, con- 'troller arm 69 to the feed wire 73, to the bus bar 66 and to the generator 65. When opposite end of the table by a wire 80, said electro-magnets being connected by a wire 81' to the bus bar 67 The circuit for energizing the electr'o-magnets to lock the turntable in adjusted position is, as'follows: from the generator 65 through the bus bar 67, wire 81 to the electro-magnets 63 at one end of the table, wire 80 to, the electromagnets at the opposite end of the table,

wire 78 to the contact 0, controller arm 69 to wire 7 3, bus bar 66 to'the generator 65.

What 'I claim, is:

1. In a switching appliance, a shiftable turn table provided with a track, a plurality of tracks from which traveling bodies are shifted to a position upon the. track of the turn table, chuck blocks one set for each track, a spring controlled mechanism for normally positioning said blocks over the treads of the rails of the tracks, and electrical magnetic means carried by the turn table and adapted to actuate said mechanism to shift the blocks from ofi" the treads and further held to said mechanism by the attractive force thereof to hold the track of the table in alinement with that track of said pluralit of tracks having the blocks removed trom the treads thereof.

2. In a switching appliance a shiftable turn table provided with a track, a plurality of main tracks leading to the turn table, chuck blocks for each of said main tracks, a spring controlled mechanism for normally positioning the blocks for each track over the treads thereof and including a piston, and electrical magnetic means carried by the table and adapted to actuate said mechanism to shift the blocks from off the treads and further held to said mechanism by the attractive force between the magnet and piston to hold the track of the table in alinement with that main track having the blocks removed from the treads thereof.

3. In a switching appliance, a shiftable turn table provided with a track, a plurality of main tracks leadin to the table, means associated with each of said main tracks for arresting the shifting of rolling stock from off a main track until the track registers with a main track, controlling mechanisms for normally maintaining said means upon the treads of main tracks, and means car'- ried by the table and adapted to actuate a controlling mechanism when the track of the table registers with a main, track to shift the means of the latter to an inoperative position and to further in connection with said" mechanism-maintain the track of the table in alinement with that main track from which the arresting means has been shifted;

In testimony whereof I afiix my signature in the presence of two witnesses.
